COVER FOR MILK-BTTLES.

Specication o Letters Patent.

Patented Oct. 19, 1915.

Application filed May 26, 1914. Serial No. 841,052.

To all whom t may concern:

Be it known that I, PAsQUiNo FERRARI, citizen of the United States,residing at Fall River, in the countyof Bristol and State ofMassachusetts, have invented certain new and useful Improvements inCovers for -Milk-Bottles, of which the following is a specification.

My invention relates to new land useful improvements in closure caps fordifferent types offliquid containers and has particular reference tothose which are employed in sealing milk bottles.

The principal object of my invention is to provide for a milk bottle aclosure which consists essentially in a body disk of cardboard orsimilar material and an apron which is secured thereto and is formedfrom relatively stiff and heavy paper.

A further object is to so crimp that portion of the apron which isadjacent the edge of the body disk that an inwardly extending lip orflange is formed over the upper face of the disk and in spaced relationthereto so that any dealer using the closure may readily insert anordinary cap bearing his own trade-mark or insignia by merely engagingsuch a cap under the flange or lip.

A still further object and one `of equal importance with the foregoingis to crimp the peripheral portion of the apron to producean annular rimwhich depends from the body disk and is adapted to engage against thecustomary bead upon the upper edge Vthe following specification and thenmore particularly pointed out in the claims which are appended heretoand forma part of this application.

With reference to the drawings, wherein there has been illustrated thepreferred embodiment of this invention as ijt'is reduced to practice andthroughout the several views, of which similar reference charactersdesignate corresponding parts,

Figure 1 is a perspective view4 of the neck of a milk bottle with `theclosure in position thereon; Fig. 2 is a view of the blank from whichthe skirt of the closure is formed; Fig.v3 is a plan View, showing thebody disk of the closure in position on the skirt; Fig.` 4 is a sectiontaken diametrically through the closure and illustrating the first stepin the shaping of the skirt; Fig.'5 is a section taken diametricallythrough the closure after. the skirt has' been completely shaped. t k

Asillustrated in Fig. l.I particularly of the accompanying drawing, myinvention consists essentially in a circular body disk l() and an apronor skirt 11 Which is formed preferably of relatively heavy andcomparatively stiff paper, such' as is commercially known as wrappingpaper.

'The body disk l0 is, in its preferred form, fashioned from relativelythick cardboard of the oil impregnated'type such as is ordinarily usedin making the well known milk bottle cap. IVhile it may be found, insome instances, desirable to imprint the name of a dealer on the bodydisk sothat litis not necessary to apply a separate disk bearing thedealers trade-mark or other in` sigma, it has been found morepractical,`

when manufacturing the closures in large quantities, to make'the bodydisks of plain cardboard since by following this procedure a larged-uantityv of the closures may be made" and distributed to'any desirednumber of diderent dealers.

The skirt or apron 1l is, as best shown in detail in Fig. 2, formedfromra single sheet of heavy, stiff paper, which is first cut tocircular form and is then-notched or scalloped'on its periphery tosimulate the outline of an 'ordinary ratchet disk. The purpose in thusforming the periphery of the skirt blank will be hereinafter more fullydisclosed in that portion of the specificationtallic fastening clip ofany type may be employed instead of an adhesive. After the disk has beenproperly attached to the apron, the portion of this latter member whichis adjacent the edge of the disk, is crimped, as illustratedparticularly in the sectional view of Fig. 5, to form theinwardlyextending lip or flange 12, which is spaced from the upper faceof the disk and extends inwardly beyond the limits of the edge thereof.The material of the apron is next creased at the extreme 'inner edge ofthe lip 12 and is directed outwardly and downwardly, producing thedepending rim, indicated in Fig. 5 by the numeral 13. This rim is, asstated, annular in shape and is formed by creasing the outer edgeportion of the skirt along a number of fold lines as illustratedparticularly in the blank view of Fig. 3. It will be noted uponreference to this figure that there extends inwardly from the apex ofeach tooth-likeV projection or notch 14 of the blank a dotted line, andthat immediately adjacent each one of these dotted lines there is asecond dotted line which extends from the inner end of the adjacentnotch. These two dotted lines, which extend from each tooth and adjacentnotch, intersect at a point lying within a circle 15, which represents,in Fig. 3, the inner edge of the disk 10. y

It is now to be noted by reference to Fig.

5 particularly that the triangular fields 16,`

which are comprehended between the various pairs of fold lines, arearranged, when the member 13 has been completely shaped, between theoverlapping terminals of those portions of the skirt which are includedbef tween the several notches and teeth.

Inasmuch as the fields between the various pairs of fold lines aretriangular and are arranged with their base portion outermost, it isapparent that the lower edge of the rim 13 will be of a diameterlessthan the diameter of the upper portion of the rim and that for this.reason, the lower edge of the rim, when applied to the milk bottle, willengage beneath the lower edge of the annular rib or flange suchas iscustomarily provided for all standard milk bottles.

In concluding the description of myF invention, it remains only toexplain that when the closure, illustrated in Fig. 1, has

'been applied to the bottle, the dealer may it is desired to emphasizethe fact that various minor changes in detailsv of construction,proportion and arrangement of parts may be resorted to, when required,without sacrificing any of the advantages of this invention, as definedin the appended claim.

Having thus described the invention, what is claimed as new is:

A bottle closure including acircular skirt, a circular body disk securedto the center of the skirt, the said skirt being crimped adjacent theperiphery of the disk to provide an annular lip, laterally spaced uponone side of the disk and extending inwardly thereover, the said lipbeing adapted to engage over the periphery of a second disk adapted toseat upon said rst mentioned disk, the outer margin of the skirt beingfolded along pairs of diagonally extending fold linesto produce adepending rim consisting of a plurality of contiguous overlappingtrapezoidal sections, the,y periphery of the skirt being provided with aseries of circumferentially spaced scallops forming the base edges ofsaid sections.

ln testimony whereof I aflix my signature in presence of two witnesses.
